Sea Chest Cleaning & Inspection
ROV-based cleaning and inspection of sea chests removes marine growth, debris, and blockages that can restrict cooling flow and impact vessel performance. Controlled cleaning methods restore operational efficiency while minimising disruption and eliminating the need for diver intervention.
Following cleaning, high-definition inspection captures clear visual evidence of internal structure, coatings, gratings, and pipework condition. The resulting imagery and reporting support system reliability, preventative maintenance planning, and class or operator requirements.
Propeller Inspection
Targeted propeller cleaning removes fouling and marine growth that reduce hydrodynamic efficiency and increase fuel consumption. The process restores blade performance and supports improved vessel speed, manoeuvrability, and operational economy.
Once cleaned, high-resolution inspection assesses blade condition in detail, identifying cavitation erosion, impact damage, edge deformation, and coating breakdown. Structured outputs provide engineering-ready evidence to inform repair decisions and performance optimisation strategies.
Propeller & Shaftline Cleaning
ROV-based propeller and shaftline inspection provides a detailed visual assessment of blades, hub, tailshaft, stern tube, and associated components without the need for drydocking. High-definition imagery captures condition across critical areas, supporting early identification of damage, fouling, misalignment, or seal concerns.
The inspection delivers clear, structured evidence to support maintenance planning, class discussions, and operational assurance. Findings assist operators in addressing defects proactively, optimising performance, and maintaining drivetrain integrity while minimising downtime.
Captured imagery supports evaluation of corrosion, coating condition, deformation, and mechanical damage. Inspection findings assist operators in planning maintenance actions, addressing defects early, and maintaining safe vessel operation.
Rudder General Visual Inspection (GVI)
ROV-led rudder inspection provides a comprehensive visual assessment of blade surfaces, welds, pintles, and associated structures. The survey is conducted methodically to ensure clear coverage of critical areas affecting steering performance and structural integrity.
Captured imagery supports evaluation of corrosion, coating condition, deformation, and mechanical damage. Inspection findings assist operators in planning maintenance actions, addressing defects early, and maintaining safe vessel operation.
The resulting data supports class compliance and long-term asset integrity programmes by identifying under-protected zones or anode depletion. Findings can inform maintenance planning, ICCP adjustments, and proactive corrosion management strategies.
Cathodic Protection (CP) Measurement
In-water cathodic protection measurement verifies the effectiveness of corrosion protection systems across hull structures and critical components. Using calibrated equipment, we record CP potentials to confirm whether protective thresholds are being achieved.
The resulting data supports class compliance and long-term asset integrity programmes by identifying under-protected zones or anode depletion. Findings can inform maintenance planning, ICCP adjustments, and proactive corrosion management strategies.

Discharge Cleaning
ROV cleaning of discharge outlets removes marine growth and obstruction build-up that can restrict system flow and affect performance. Targeted cleaning improves operational reliability and reduces the risk of system inefficiencies.
Following cleaning, visual inspection confirms outlet condition, coating integrity, and structural status. Clear reporting provides assurance that discharge systems remain unobstructed and fit for continued service.
Crossweld Close Visual Inspection (CVI)
Close visual inspection of cross welds and structural joints focuses on high-risk areas where stress concentration and coating breakdown can occur. High-resolution imaging enables detailed examination without diver intervention.
Inspection outputs support early detection of corrosion, cracking indicators, and mechanical damage. The structured reporting format provides condition evidence suitable for engineering assessment and class engagement.
Fairlead General Visual Inspection (GVI)
ROV-based inspection of fairleads and associated mooring structures assesses wear surfaces, alignment, corrosion, and overall condition. The survey supports safe mooring operations by identifying deterioration that may affect load paths.
High-definition imagery enables detailed review of structural integrity and coating performance. Findings support preventative maintenance planning and reduce the risk of operational disruption during berthing or anchoring.
Anchor Chain Cleaning
ROV-based chain cleaning removes marine growth and debris to restore full visual access along the chain length. Improved visibility is essential for accurate condition assessment and wear evaluation.
The cleaning process supports subsequent inspection by revealing corrosion, deformation, and mechanical damage that may otherwise remain concealed. This enables more reliable maintenance planning and integrity monitoring.
Chain Link Measurement
Calibrated ROV systems are used to measure anchor chain link dimensions and assess wear against allowable tolerances. Measurements are taken systematically to ensure consistency and accuracy across inspected sections.
Quantifiable data supports compliance verification, replacement planning, and long-term asset management decisions. The resulting documentation provides objective evidence for operators, engineers, and class stakeholders.
Bilge Keels & Keel Ends
Bilge keels and keel ends sit at structurally significant points on the hull and are prone to impact damage, weld cracking, coating breakdown, and localised corrosion — often going undetected between drydock cycles. ROV inspection provides clear, close-range visual access along the full length of the bilge keel and across the keel end terminations without the access restrictions that make diver surveys difficult in these areas.
High-definition imaging captures weld line condition, physical deformation, coating integrity, and any evidence of cracking or material loss. The resulting report supports class compliance, informs repair prioritisation, and provides a documented baseline for condition monitoring between surveys.
The cleaning process supports subsequent inspection by revealing corrosion, deformation, and mechanical damage that may otherwise remain concealed. This enables more reliable maintenance planning and integrity monitoring.
Frequently Asked Questions
Learn more about our UWILD solutions
Clear answers to common questions about UWILD approvals, scope, methodology, and how in-water inspection supports class compliance while reducing operational disruption.
What is a UWILD inspection?
UWILD (Underwater Inspection in Lieu of Drydocking) is an in-water survey carried out to satisfy class requirements without the vessel entering drydock. It provides documented evidence of hull, appendage, and structural condition while the vessel remains afloat.
Can UWILD replace drydocking entirely?
UWILD can replace specific scheduled drydock inspections where class approval is granted. Approval is subject to vessel type, condition history, and survey scope, and must be agreed with the relevant classification society.
What areas are typically covered during a UWILD?
UWILD inspections commonly include the hull, sea chests, rudder, propeller, shaftline, thrusters, and other critical underwater structures. The scope is agreed in advance with class to ensure compliance requirements are met.
How is a UWILD inspection carried out?
ROV systems are deployed alongside the vessel to capture high-definition imagery and structured inspection data. The survey is conducted methodically to ensure complete coverage and clear documentation of structural condition.
What deliverables are provided following a UWILD?
Deliverables include a class-ready inspection report, annotated imagery and video, and organised condition findings. These outputs support class review, maintenance planning, and engineering decision-making.
What are the advantages of UWILD compared to drydocking?
UWILD reduces downtime, avoids drydock scheduling delays, and minimises operational disruption. It enables vessels to maintain operational readiness while still meeting inspection and compliance requirements.
